 impresso flavo-pubescente ; elytris utrinque linea curvata basali, fascia transversali lateral! ad trientem 

 longitudinem, alteraque obliqua apicem versus, flavis, medioque lineola tenuissima lateral! transversa alba ; 

 scutello suturaque basi immaculatis ; clypeo sat elongato et angusto ; tborace paullo ante medium valde

Eab. Panama, Bugaba, Volcan de Chiriqui 3000 feet [Champion). 



Two examples only, one of each sex. The yellow lines of the elytra evidently vary 

 in extent, and appear to be the rudiments of the more developed lines of similar colour 

 in the allied species.

CCELOCRATUS. 



Coelocratus, Burmeister, in Germar's Zeitschr. iii. p. 242 (1841) ; Handb. der Ent. iii. p. 767. 



One species only has hitherto been described of this genus, from " the interior of 

 Northern Brazil." I refer the following, smaller, Mexican species to the genus 

 owing to the very similar form of the clypeus (in which Coelocratus differs from all 

 other genera of Trichiidse), viz. transverse-quadrate, with straight front edge and equally 

 raised fore and lateral margins. The Mexican insect also agrees in the form of the 

 thorax and elytra, and in the anterior tibiae having two outstanding teeth in both sexes, 

 but it differs in the middle tibiae of the male not being bowed. 



1. CoBlocratus senescens. (Tab. XXIII. fig. 13.) 



Oblongo-ovatus, parum convexus, toto erecte (apud caput et tboracem multo longius) pubescens, viridi-asneus vel 

 obscure seneus, nitidus ; elytris opacis, testaceo-rufis vel fulvis, sutura et marginibus, vitta utrinque angusta 

 recta, antice abbreviata, dorsali, vittaque latiore curvata et intus bilobata laterali, obscure viridi-seneis, 

 interdum vagis et subobsoletis ; tborace fere sicut in Trichio fasciato rotundato, aDgubis posticis vix 

 distinctis, antice angustato angulis acutis, sat dense punctato ; elytris striis nonnullis subtilissimis et 

 sparsim subtilissime punctulatis; pygidio <3 longe fulvo-villoso, subverticali, § breviter pubescente, 

 marginibus dense albido-squamulosis.
